2 Claims.

This invention relates to a soil pipe joint runner.

In assembling sections of soil pipe the conventional practice is to insert the spigot end of one section of pipe into the bell end of an adjoining section and after oakum or the like is caulked in the bell around the spigot to fill the mouth of the bell around the spigot with molten lead or the equivalent retaining the oakum in place and forming an effective metal seal.

An object of the present invention is to provide a relatively simple and inexpensive device which can be easily and quickly applied about the soil pipe and positioned against the mouth of th bell which forms a dam or barrier over the mouth of the bell to retain the molten metal therein until it solidifies on cooling. The device also provides a spout or runner through which the molten metal can be poured into the bell.

Another object of the invention is to provide a device having the above mentioned characteristics wherein the runner or spout, which is formed of metal, is spaced inwardly from the ends of the compressible or rubber-like material that forms the body of the barrier but which is so arranged that on tightening the device in place mutually engageable ends of the compressible material will be engaged and compressed to effec- I tively form a leak-proof seal therebetween.

A further object of the invention is to provide a soil pipe joint runner which is so designed as to be easily and quickly applicable and adjustable to pipes of various sizes.

With the foregoing and other objects in view, which will be made manifest in the following detailed description and specifically pointed out in the appended claims, reference is had to the 'accompanying drawings for an illustrative embodiment of the invention, wherein:

Figure 1 is a perspective view of the soil pipe joint runner embodying the present invention 11- lustrating the same as applied to the joint between adjoining sections of soil pipe;

Fig. 2 is a vertical section taken substantially upon the line 2-2 upon Fig. 1;

Fig. 3 is a vertical section taken substantially upon the line 3-3 upon Fig. 2;

Fig. 4 is a top plan view illustrating a modified form of construction in applied position on soil pipe; and

Fig. 5 is a vertical section taken substantially upon the line 5-5 upon Fig. 4.

Referring to the accompanying drawings wherein similar reference characters designate similar parts throughout, the improved soil pipe joint runner as illustrated in Figs. 1, 2 and 3 consists of a pipe encircling and barrier forming member generally indicated at In. This section is formed of neoprene or similar rubber-like resilient material so as to be readily compressble and deformable. The member in is in the form of a split ring the mutually engageable ends of which are indicated at H and I2. Near one end of the split ring there is secured as by bolts [3 a flanged metal member 14. This metal member has a peripherally arranged portion l5 and a flange I'B designed to overlie the outer side of the split ring l0. Both the peripheral portion l5 and the flange l6 extend beyond the end ll as indicated at IS on Fig. 3 thus forming a projecting portion that may function somewhat as a guide for the end l2 when the two ends ll and H are brought together. I

The metal member l4 provides a runner or spout l9 that is inclined downwardly and inwardly and adjacent this spout there is a notch 20. This notch is designed to receive a cross bar 2| mounted on the swinging ends of two links 22 and 23. These links in turn are pivotally mounted upon a handle 24 that is pivoted as at 25 on a metal member 26 that is mounted on the end 12 of the split ring ID as by bolts 21. As will be apparent from the dotted line position shown in Fig. 3, the bar 2i may be engaged in Or entirely removed from the notch 20 but when in position therein on swinging the handle 24 downwardly the links 22 and 23 will draw the two metal members l4 and 26 towards each other with considerable mechanical advantage. In so doing the ends l I and I2 will be forced into firm engagement with each other and as the material of the split ring I0 is highly compressible or resilient these ends when engaged will effectively prevent the escape of any molten metal between them. The internal diameter of the ring in is slightly smaller than the exterior diameter of the section of soil pipe S to which the device is applicable.

In the use of the device the spigot end of the section S is inserted in the bell B of an adjoining section. Oakum 0 may then be caulked in place in the bell. The device can then be applied to the section S by disengaging the bar 2| from its notch 20 allowing the split ring In to be opened wide enough to permit of its application to the section S. Then on reengaging the bar "2| in its notch 20 and swinging the handle '24 downwardly the two ends H and I2 will be forced towards each other and the ring l0 contracted about the pipe section. The device is positioned closely adjacent the bell B and molten metal such as lead can be poured into the bell against the oakum through the runner is. As soon as the metal has solidified on cooling the runner may be removed in the reverse manner from its method of application thus completing the formation of the joint.

In the form of construction illustrated in Figs. 4 and 5 there is a section of neoprene or similar rubber-like material indicated at 30 which adjacent one end thereof has a metal member 3| secured thereto such as by bolts 32. The metal member 3! provides the pouring spout or runner 33. In this form of construction, the adjacent end 34 instead of being radially arranged as in the case of the end H is beveled or arranged approximately tangent to its interior curvature. The other end of the section 30 indicated at 35 is adapted to be drawn tightly thereagainst in any suitable manner such as manually and when this end is drawn tightly and held against the beveled end 34 it will form a similar leak-proof seal. The molten metal can be run into the bell of the joint through the runner 33 while the section 30 is thus held around the section S. The advantage of this form of construction resides in the fact that it is applicable to pipes of various sizes. With smaller size pipes, a greater length of the end 35 can be withdrawn in holding it tightly against the end 3d and, conversely, on larger size pipes, a shorter length of the end 35 is available for pulling the member 30 tightly around the pipe.

The invention has been described with reference to soil pipe and it is intended that soil pipe is to be used in a broad definition so as to include all types of pipe which would be used in the soil and the invention is also applicable to cast iron or water or gas pipe or the like.

Reference has been made in the specification to the use of a compressible or rubber-like material and also to neoprene and it is not intended to be limited to rubber or neoprene but any resilient heat resistive material which would have physical properties somewhat close to neoprene or other rubber-like materials are intended to be included in the scope of the invention.

Various changes may be made in the details of construction without departing from the spirit and scope of the invention as defined by the appended claims.

I claim:

1. A soil pipe runner comprising a split ring of. resilient compressible material adapted to be placed in encircling position around a soil pipe, a metal fitting secured to one end of said ring providing a laterally directed spout traversing the outer ortion of the ring, said metal fitting having a side and a back lying against a side and the peripheral surface of the ring respectively and projecting in a circumferential direction beyond the end of the ring to which it is attached to form a guide for the other end of said split ring, the side, back and spout being disposed outwardly of the inner circumference of the ring, a metal fitting secured to but spaced from the other end of said split ring to leave a projecting portion receivable in the guide, and means for drawing said metal fittings towards each other to tighten the ring about the pipe.

2. A soil pipe runner comprising a split ring of resilient compressible material adapted to be placed in encircling position around a soil pipe, a metal fitting secured to one end of said ring providing a laterally directed spout traversing the outer portion of the ring, said metal fitting having a side and a back lying against a side and the peripheral surface of the ring respectively and projecting in a circumferential direction beyond the end of the ring to which it is attached to form a guide for the other end of said split ring, the side, back and spout being disposed outwardly of the inner circumference of the ring, a metal fitting secured to but spaced from the other end of said split ring to leave a projecting portion receivable in the guide, the last-mentioned fitting having a handle pivotally mounted thereon, links pivotally connected to the handle, and a bar carried by thelinks engageable with a notch on the first-mentioned fitting adjacent the spout.
